PLOW.

Application filed September 24, 1917. Serial No.

To all whom it may concern:

Be it known that I, OLOF SWANSON, of Kindersley, in the Province ofSaskatchewan, Canada, a subject of the King of Great Britain, and usefulImprovements in Plows, of which the following is a specification. y

My object is to devise a plow especially adapted for use in breakingheavy land and in stubble plowing. I attainmy object by employinginstead of a single side mold board with its share a plurality of narrowmold boards each with its own share and landside and each connected to aseparate beam, the beams being suitably braced and connected.

In detail the plow is constructed substantially as hereinafter moreparticularly described and illustrated in the accompanying drawings inwhich- Figure 1 is a plan View of a plow constructed in accordance withmy invention;

Fig. 2 a side elevation of the same;

Fig. 3 a side elevation of a single landside with its flanges;

Fig. 4: a plan view of three land sides, mold boards, sole plates andshares in proper relationship for the turning of a furrow.

Fig. 5 a plan View of a landside, moldboard, sole plate and share asdesigned for shallow plowing; and

Fig. 6 a cross section through a landside, sole plate and moldboardshowing particularly the wedge for adjusting the position of the moldboard.

In the drawings like numerals of reference indicate corresponding partsin the different figures.

1 is the main plow beam, which is of ordinary construction, providedwith a plurality of auxiliary beams at its rearward end. The rear ends 3of these branches are curved downwardly in echelon formation as shown.Each of the auxiliary beams has an offset lug 4 formed at its forwardend adapted to be bolted either to the main beam or to the intermediateauxiliary beam as the case may be. It will be noted that a plurality ofbolt holes 5 are formed so that the relative positions of the brancheslongitudinally of the plow may be varied according as the plow is to beused in breaking or in stubble plowing.

Braces 6 are provided for the rearward ends of the branches, whichbraces are bolted in place, a plurality of bolt holes 7 being formed inthe main plow beam and inter- Specification of Letters Patent.

mediate auxiliary beam so that the braces may be accommodated to thelongitudinal ad ustment aforesai To the lower end of each plow beam issecured a plate 8 forming a landside. Each 8 has a sole plate flange 9and a moldboard flange 10 formed thereon. The sole plate 11 and th eplow share 12 will be formed integral with one another and are bolted tothe flanges 9 and 10 as shown. The' sole plate is narrow, as is also theshare, the forward edge of the latter being preferably at right anglesto the plow beam.

To each moldboard flange is secured a narrow upwardly and rearwardlydirected slat 13 forming an independent mold board. These moldboardslats, however, are twisted and curved in the direction of their lengthand are differently shaped so that they act in turning a furrow as partsof a single moldboard.

The spacing between the separate sole plates and land sides, asappearsfrom the plan view of Fig. 4 increases slightly from front torear, that is, the land sides are not parallel, which materially assiststhe plow in cleaning itself and prevents clogging.

It will be appreciated from the drawings and description that while eachof the plow beams is completely equipped with landside, sole plate,share and mold board, yet these parts all cooperate in the turning of asingle furrow. Owing, however, to the spacing of the parts, I find thatthe plow will cut a 16" furrow in heavy land with four horses, whileother plows will take five to six horses and at times cannot be used atall. I also find that by using the separate shares, moldboards andlandsides that there is practically no side draft to the plow. I alsofind that the plow will work satisfactorily at depths stay in thefurrow.

Instead of the bottom of the furrow being flat and hard as the ordinaryplow leaves it, the bottom is left loose to a depth of one to twoinches.

The plow is shown as set for breaking. In stubble plowing the auxiliaryplow beams will be shifted rearwardly as hereinbefore described. Soalso, for stubble plowing the angle of each moldboard 13 requires to bechanged. This is effected by employing a wedge 14, which may be boltedbetween the shown in Fig. 6.

For shallow plowing, the moldboard pro vided with the wing 15 ispreferred. he plow share alsois preferably provided with the triangularlateral extension 16.

What I claim as my invention is 1. In a plow, the combination of aplural ity of spacedbeams, the rear ends of which turn downward inechelon formation; a.

share, a narrow sole plate, a mold board,

and a landside connected to each beam-,the-
